Rubber bushing kit PLEASE!
 

I see thousands and thousands of posts on here for poly bushing kits,
but where the heck does one go about obtaining a RUBBER bushing kit
(i.e. stock) for a 1991 Cherokee 4WD?! It's my wife's jeep and with
the Rancho 5000's that are already on there the ride is somewhat less
than forgiving, so I'm not about to put poly bushings on there and
make it even more stiff.

Somebody please help!
